PUMP.

Application filed September It the purpose of the present invention to provide, in a fluid pump, a construction wherein a rotor is mounted eccentrically of the cylinder, with radial vanes,yieldably connected, carried by the rotor, so that as the intake of fluid enters the cylinder at one portion, it will impact against one of the vanes which acts as a piston, thereby im' parting rotation to the rotor, the fluid exhausting at a corresponding portion of the cylinder, that is, on the opposite side of the vertical axis of the cylinder.

Another purpose is to provide a rotor with a radial cavity intersecting the center of the rotor for carrying the radially disposed vanes which are resiliently connected, so that the vanes may move toward and from each other and wipe against the inner circumference of the cylinder when passing through a smaller part of the chamber of the cylinder when the vanes areeccentric to the center of the cylinder. I

It is to be understood that the particulars herein given are in no way limitative and that, while still keeping within the scope of the invention, any desired modifications of detail and desired proportions may be made in the apparatus according to the circumstances.

The invention comprises further features and combinations of parts to be hereinafter set forth, shown in the drawings and claimed.

In the drawings:

Figure 1 is a longitudinal sectional view through the improved pump, showing the.

rotor mounted in the cylinder and showing the shaft as passing through a stufing box or gland.

Figure 2 is a sectional view on line 22 of Figure 1.

. Figure 3 is a detail view of the rotor its shaft.

Figure 4 is a face view of the rotor. Figure 5 is a detail View of the vanes. Referring to the drawings, 1 designates the cylinder which may be anysize and hape, preferably cylindrical, and constructed of any suitable metal. The cylinder '1 has an eccentrically disposed cylindrical hub 2 for the reception of the drive shaft 3 which carries an integral rotor 4 which rotates eccentrically within the cylindrical chamber 5 of the cylinder 1 which is closed by means of a cylinder head 6. The cylinder and ' head is bolted or otherwise fastened at 7 to shown in full lines.

the cylinder. A. suitable packing 8 is interposed between the cylinder headand the wall of the cylinder to preclude leakage.

The rotor is provided with a radial recess or cavity 9 intersecting the center of the rotor for the reception of the vanes 10 which constitute pistons. Each vane is of a width equal to the width of its cylinder '1, as shown clearly in Figure 1, so that the vanes may wipe against the opposed faces of the chamber 5. The adjacent edge portions of the vanes have cylindrical bores or recesses 11 for the reception ofan expansion coil spring 12 which tends to force the vanes radially of the rotor and retain their remote edges 13 in contact with and wiping against the cylindrical surface of the chamber When the vanes are in the position shown in full lines in Figure 2, they are operating across the center of the cylinder but when the vanes are in the positions shown in dotted lines, that is, just prior to reaching the full line position and after passing said full line position, the vanes are operating in a direction eccentric to the center of the cylinder. However, at all times the vanes are operating across the center of the rotor.

The rotor is provided with an intake 13 and an exhaust 14 and where the shaft 3 passes beyond the hub 2 of the cylinder, it is mounted in a packing box or gland 15, there being a recess 16 for the reception of a key or feather for mounting the pulley (not shown) on theshaft. The cylinder has a base, whereby the cylinder may be mounted upon a foundation.

The intake may receive a supply of fluid from any suitable source through a pipe 17 while the fluid in exhausting through the exhaust duct 14 may be carried off to a suitable location by means of a pipe 18.

The fluid passing through the intake 13 impinges against one of the vanes, the vanes being eccentric to the center of the cylinder and therefore compressed toward each other,

thereby imparting revoluble movements to the rotor. The fluid behind the vane then passes out through the exhaust 1 1 after the vane passes the exhaust, it being at the time when the vanes are 1n the positions The invention having been set forth, what is claimed is: r

A pump comprising a cylinder having an eccentrically disposed hub, a detachable head closing the cylinder on the opposite side from the hub, an overhung rotor of a Width corresponding to the Width of the cylinder and of a diameter materially less than the latter, the rotor having a shaft journaled in the hub and having a continuous diametrical slot opening on that face opposite the shaft, and vanes carried in the slot of the rotor and in edge contact with the inner peripheral surface of the cylinder, the vanes being provided With a spring interposed between them and yieldingly forcing them into engagement with the peripheral Wall of the cylinder, the cylinder head serving as a lateral retaining means to retain the vanes in the slot of the rotor, the cylinder being provided with in take and discharge ports disposed respec tively on opposite sides of the shortest radial line from the axial center of the hub to the periphery of the cylinder.

In testimony whereof he aifixes his signa- 20 ture.
